Medical technologist deals with pre analytical, analytical and post analytical testing of patient's specimens. Medical technologists generate accurate laboratory data that help in detection and treatments of many diseases. There can be different types of medical technologists depending upon their area of specialization. In small labs medical technologists perform many different types of test but while those in large labs often specialized.
* Clinical chemistry technologists: Are those who analyze the chemical and hormonal composition of body fluids. They are specialized in field of chemical chemistry. Under this, many other tests can be categorized like general routine chemistry tests, endocrinology, pharmacology and toxicology.
* Blood bank technologist: these technologists type blood and match it to donor units of blood transfusions, these medical technologists has to be accurate and organized as even small mistake can be dangerous and fatal.
* Urinalysis: it is one of the oldest tests taken in laboratory. A medical technologists in urinalysis checks physical properties of urine like color and turbidity. They also look at chemical composition of urine, which involves test for blood, protein, glucose and white blood cells. Medical technologists also have to look for crystals blood cell and bacterial that is not supposed to be in urine.
* Cytotechnologists: these medical technologists have specialization in microscopic screening of cells for various abnormalities.
* Hematology and coagulation: hematology is study of blood. Medical technologists in hematology detect number and type of white blood cells with help of microscope. With help of cell counter, they count cells. Medical technologists can also tell ratio of RBC to plasma, which is known as hematocrit. CBC i.e. complete blood count is also done using this cell counter.
Owing to the numerous specialized fields in healthcare, many types of medical technologists are required by clinics or hospitals.
Coagulation is study of patient's hemostasis; it is stopping of blood flow from injured blood vessel. Medical technologists measures time required blood to clot to determine system is working properly or not. Medical technologists can detect factor that is not working properly. The two important tests done in coagulation are Protime and the Activated Prothrombin Time. If some anticoagulant is given to patient to prevent unnecessary clots then medical technologists can help in determination of dosage of medicine by doing those two tests.
